' perspective view JOHN 'M. FEDDERS, OF BUFFALO, NEW YORK, ASSIGNOR TO FEDDERS MANUFACTURING COMPANY, me, or

BUFFALO, NEW YORK, A CORPORATION OF NEW YORK.

To all whom it may concern:

Be it known that 1, JOHN M. Fnnnnns, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiator Units, of which the following is a specification.

This invention relates to improvements in the construction of the units which enter into the manufacture of radiators whereby the water circulated in gas engines is reduced in temperature and it has for its ob ject the production of radiating members for such units which can cost and still maintain the maximum radiating efiiciency of the radiators and also present a cellular appearance of the radiators.

In the accompanying drawings:

Figure 1 is front. elevation, partly in section, of several units of the core of a radiator. Fig. 2 is a horizontal sectiontaken on line 22 Fig. 1. Fig. 3 is a fragmentary of one of the radiating members. Fig. i is a similar view of one of the plates forming part of one of the radiating members.

Similar characters of reference indicate corresponding parts throughout the several views.

The conduits of the radiator through which the water of the gas engine is passed for cooling the same comprise passages or tubes 1 which are arranged side ldy side and each of which is preferably constructed of two sheet metal walls 2, 2, which are corrugated so as to produce a tortuous or serpentine passage for the water.- I These two walls of each water tube are a proper distance by providing their corresponding longitudinal edges with off-sets 3, 3 which engage with each other and are connected to form a water tight joint by means ofsolder or other suitable means.

The opposing walls of adjacent water tubes form the outer walls of a radiator unit between which is arranged a radiating member which divides the space between these outer Walls into a plurality of air passages 4, 4 and thereby aids in dissipating the heat of he water passing through the water Specification of Letters Patent.

tubes. This radiating member forms the subject. of the present invention and in its preferred form the same is constructed as follows:

Between the outer walls ofe'ach unit and ad acent to opposite longitudinal edges thereof are arranged two end supporting sections each of which comprises a plurality of longitudinal webs 5, and a plurality of pairs of transverse plaits 6, 6 which are arranged in a longitudinal row on opposite sides of the webs. The'two plies of each plait are connected at their outer edges with each other and engage with the bottom or valley of an adjacent corrugation of there- I spective outer wall. The inner end of one ply of each-plait is-connected with the inner end of one ply of the companion plait, while the inner end of the other plymf each plait is connected with the adjacent side edge of one of the longitudinal webs. The several longitudinal webs and transverse plaits are preferably formed of a single sheet of metal any suitable manner.

Between the end supporting sections of each radiating member and the adjacent outer walls of a radiating unit is arranged a plurality of transverse radiating plates 7 which are constructed of sheet metal. At its opposite ends each of these radiating plates is provided with longitudinal slots or notches 8 extending inwardly from the ends thereof so as to-form two end tongues 9, 9 at each end of this plate. In assembling the radiator unitone of the tongues 9 of a pair at eachend of the radiating plate is inserted inthe seat or space formed between the plies 0f one plait of a pair on one of the end supporting sections, while the other tongue of this pair engages with the seat or space between the two plies of the companion plait of this end section. In order to stiffen each of these radiating plates and serve as a stop /for limiting the entrance of a pair of tongues into the seats ofa pair of plaits, this plate is provided .adjacent to the inner ends of its notches or slits 8 with transverse beads 10 which are adapted to engage the inner sides of the end supporting sections, as best shown in Figs. 2 and 3. By

each radiating unit can be rapidly assem I bled and still bring the outer ends of the tongues always flush with the end sections so. as to produce a neat and finished appearance. i

In order to permit the intermediate portions 11 of the longitudinal edges of the radiating plates to bear against the intermediate parts of the adjacent; valleys ofthe outer walls of the radiating unit, the central part of each of these plates. is made suficiently wide for this purpose but the end portions of these plates are reduced slightly as shown at 12 in Figs. 2 and 4, so as to enable the tongues to engage with the respective pairs of laits on the end supporting sections.

us end of a pair-of outer walls of a radi-.

ator unit may be connected by a fold 13 and the opposite ends thereof ma be interlocked by means of a seam 14 as s own in Fig. 1. When the several parts of a radiator unit have been thus assembled, they are retained in position relatively to each other by soldering the outer ends of the end sections and.

radiating plates to each other and to the outer walls ofthis unit. This solder connection between the several pairs of tube walls and radiating members is preferably effected in the usual and well known manner by dipping opposite sides of the completed radiator core in a bath of solder.

A radiating member for radiator units thus constructed can be produced at comparatively low cost inasmuch as it consumes a minimum amount of metal and yields a maximum radiating efiiciency.

I claim as my invention:

A radiator unit comprisin two outer walls, and an intermediate radiating member comprising and supporting sections arranged lengthwise between said walls at opposite longitudinal-edges thereof, and a lurality of transverse plates arranged at intervals between said walls and each supported at its opposite ends on said supporting sections.
